IJOGGING DEVICE.
Application filed December 23,1926. Serial No. 156,667.
This invention is directed to stop means operative more particularly with dogging mechanism for the knees of saw mill carriages whereby in any and all possible adjustments of such knees and dogging mechanism, the dogs will be prevented from proj ecting into the saw line.
conventionally, a saw mill carriage is provided with two or more knees which are adj ustable on the carriage through the use of the set works for gradually advancing the log or cant to the saw for the sawing operation. These knees are provided with dogs, so-called, which are elements operated in various ways for engaging the upper and lower portions or the log or cant and holding the same in more or less fixed relation to the knee While the saw is operating to make the successive cuts in such log or :ant. The socalled dogging devices have been devised in different forms and arrangements, in some instances being operative in advance of the knee on a particular line for the most'eltective engagement with a log. In other instances the dogs have been arranged so that they may be selectively positioned for operation beyond the face of the knee in either of two predetermined paths, one being that at which the dog is projected at the maximum distance beyond the face oitthe knee and thus serviceable for engaging round logs, and another being that in which the dogs are withdrawn for operation in. a path at a minimum distance beyond the face of the knee and thus serviceable for engaging.
boards or canls. Furthermore, in those types of devices where the dogs are adapted for either a maximum or minimum position selectively, various types of mechanisms have been provided for securing this selective maximum or minimumposition.
In order, therefore, to provide a means for solimiting the mechanism that the dogs cannot be projected into the path oi? the saw, it is apparent that the problem is one oi? accoimnodating the limiting means to the several varieties of dogging mechanisms both wherein the d ogs operate in a fixed plane only and wherein the dogs operate in either a maximum or minimum plane at will.
The invention, therefore, consists in prov idi [1 means whereby the dogs are prevented i' an reaching tl' saw line in any possible nee and without regard to are capable of only a single path of movement beyond the knee or are capable of a maximum or min imum path of movement beyond the knee. The invention is illustrated in the accompanying drawings, wherein:
Figure 1 is a view in elevation of a particular type of dogging mechanism wherein the dogs are adapted for maximum or minimum positions, with the improved stop arranged to prevent the dogs in either position from reaching the saw line.
Figure 2 a viewin elevation of another type of dogging mechanism wherein the dogs are adjustable for movement in a maximum or minimum position, the improved stop in this instance serving to limit the movement of the knee with the dogs in either position to prevent the dogs entering the saw line.
Figure 3 is a similar view of another construction wherein the dogs are adjustable for a maximum or minimum path of IIlOVGIIlGDl] relative to the knee, the improved stop in this instance being arranged to function to prevent the dogs reaching the saw line in either of their adjusted positions.
Figure 4: is a similar view of another type of mechanism wherein the dogs are capable of a single path of movement in advance of the knee, the stop in this instance serving to limit the movement of the knee so that the dogs in their projected positions will not encroach upon the saw line.
Figure 5 is a longitudinal sectional view on line 5-5 of Figure 1 showing the lower end of the guide in cooperation with the stop on the head block.
Figure 6 is a broken perspective of the head block" showing the stop formation.
It is to be understood that the present invention may be defined as a stop or limiting means with which a selected part or parts of the a 'iparatus on the knee will cooperate so that the dogs, when in opeative position, cannot reach the saw line. The various con.- structions illustrated in the accompanying drawings are Well known practical construc- 'tions for accomplishing the dogging operation such coi'istructions as illustrated in Figures 1, 2 and 3 being similar for the purposes of the present invention in that they provide for adjusting the dogs for a path of travel di beyond the face of the in while the i. notion shown in Finn icrovides for only one path of movement of the dogs beyond the face of the knee. It will be obvious that as the constructions wherein the dogs are capable of the two independent paths, as in Figures 1, 2 and 8, provide for this dog adjustment through materially different instrumentalities and details, the problem of providing a stop effective with these respective mechanisms must necessarily embody different details, hence the different constructions are made with a View to illustrating the invention in connection with different. types of dogging mechanisms. The respective dogging mechanisms shown in the draw ings will'be but briefly described with that I description limited largely to the details necessary for the understanding of the present invention, it being understood that the constructions shown are actually practical working constructions and have been commercially practiced as dogging mechanisms, no claim being made in this application concerning the specific dogging mechanism, except in its application to my lmprovemcnt. I 7 In the form shown in Figure 1, the knee indieated at 1 is mounted for movement on a head block 2 in any usual or preferred manner, the knee being thus ad ustable to and from the saw line indicated in dotted lines at 3'. The dogs proper indicated at 4 are mounted upon a bar 5 which, through the medium of angle levers 6, power lever 7 and power means 8, is adjusted to and from the face of the knee, whereby the dogs may operate at a maximum path beyond the face of the knee or at a minimum path beyond such knee face. As the knee is ordinarily adjustable longitudinally of the head block and toward the saw line inan identical manner and to the same extent without regard asto whether the dogs are adjusted for maximum or minimum operation, it will be evident that the knee cannot be directly limited or stopped, for if the knee were limited to prevent the dogs when in fminimum position from reaching the saw line, such knee limit would not prevent the dogs in maximum position from rcachin the saw line. Hence the knee may be said to be the fixed factor inthe dog; adjustment, that 7 is the distance movement of the knee relative to the saw line being a fixed and not a variable movement'm accordance with the dog; ad ustment, such knee cannot be directly stopped, However, there is a 1ncn1bcrhcre the bar 5wh1ch is variable, that is this bar particular dog projection may be. Obviously,
therefore, the knee remains a lixcd factor in the adjustment and the position of thc dogs relative to the face of the kncc is controlled by the movement of the bar 5, licuce this bar 5 is the variable factor in the :uljuslnn'nt. It the stop means of the prescnt invention was applied on the knee so as to sprujilically limit the knee, it is apparent that if the dogs in their minimum path were prcvcntcd from reaching the saw line by the cooperation of the knee with the improved limiting means, then such does, when projected for lhcir maximum path beyond the face of the kncc, would encroach upon the saw line, for it is understood that the article held by lhc dogs agza inst the knee is gradually advanced by thc movement of the knee to the saw line for successive cuttings. It is apparent, thcrctorc. (hut in this particular form the variable factor in the adjustment of the dogs must be the member controlled by the stop clement, hencc ,for the purpose of the present invention, the bar 5 is extended below the lower doe and below the knee to provide an abrdmcid l) and there is secured upon the head block in the path of movement of this abutment a fixed stop 10. Therefore, the advance of the knee to adjust a log, or board to the saw line is stopped whcn the abutment 9 on the bar 5 engages the stop 10. As the position of the bar 5 relative to the knee determines the operative projection of the dogs beyond the face of the kncc, it is apparent that the abutment fl is always adjusted with respect to the face of the knee in accordance with the adjustment of the dogs, that is to say that if the dogs arr advanced to their maximum. the abutment S) will bc closer to the face of the knee than if the dogs are withdrawn to their minimum position. Hence the abutment on the bar 5 will always engage the stop in the same relative position of the knee with respect to the saw line. That is, it the dogs are projected to their maximum, the moven'icnt of the knee will be interrupted farther from the saw linc than if the dogs are projected to their minimum positions, hence the dogs, whether projected at their maximum or minimum, cannot reach the saw line.
Figure 2 illustrates another type of apparatus in which the dog's are capable of maximum or minimum path of movement beyond the face of the kncc. Herc the knee. indi ated at 1], is mounted upon the hcad block 12 for the usual movement. The dogs l3 arc vcrtically guided in a guide 14. which guide is bodily movable longihulinallv of the knee in guide channels or slots 15. 'lhrou jh mechanism indicated generally at 16. and not '0- (piiring; any specific description, the docs may be adjusted to a position for maxinnuuprojcciion beyond the face of the kucc or for minimum projection, this movementof the dogs serving to move the vertical guide 14 in the guide channels 15 to and from the face of the knee for controlling the predetermined path of movement of the dogs. Here, as in the to rm shown in li i arure l, l have a variable factor in the dog adjustment, suclrin this instance being the movable guide l l. Thus the movable guide, being the variable factor in the adjustn'lent, is for the purpose of the present invention, extended. to term an abutiucnt 17 which is arranged to cooperate with a stop 18 lined on the head block. Therefore, no matter what the position of the guide, that is no matter what the projection ol the dogs beyond the taco oi? the knee, the guide abutment 17 will cooperate with the stop 18 to limit the movement of the knee in direct accord with the position of the guide, that is the projection of the dogs in any particular i nstauce.
in the form sl :wn in Figure 3 there is put vided an additional construction wherein the dogs are capable of being); adjusted for niovcmeat in a maximum path beyond the face of the looee or in a n'iinimun'i path beyond such lcnee face. In this form, the knee indicated at 19 is mounted. for movement on the head block 20 in the usual manner. The dogs 21 are bodily slidable through castings 22 which are guided, in. the vertical movement of the dogs, in guide 23 fixed to the knee. The adjustment of the dogs to secure their maximum or minimum operation is secured by bodily movin the dogs through the castings 22, the latter remaining at all times in guiding cooperation with the guide 23. This bodily movement of the dogs is secured through mechanism indicated at 24 and which may be, tor the purposes of this description, referred to as a connecting plate 25 to which both oi the dogs are directly or indirectly connected, with such plate capable oi moving in betantially rectilinear lines through pivoted links 26. Here again, we have a variable Factor in the adjustment of the dogs; that is to say the plate 25 which follows the movemeat of the dogs in that it occupies one position relative to the knee in the maximum ad 'ustment of the dogs and another position in miniumm adjustment of the dogs. There- 'orc, in the present invention the stop forminc; the present improvement is constructed as a lug 2? depending: from the plate 25 and adapted to cooperate with a stop 28 on the head bloclc. Oil. course, it is umlerslood that the lower dog is also a variable factor in the :uljustment and the lug; 27 may, if desired, depend directly from this lower dog, pre'l'ei abl y near its pivotal support. Obviously in this term the movement of the variable factor correspondiugly positions the lug 2? with respect to the face of the knee and hence the stopping function of said lug, when coo uirating with the stop 28, will limit the tarthcr movement of the knee in direct accord to the position of such lug With respect to the face of the knee. The position of the lug 27,
ct course, is directly controlled by the posi. lion of the variable factor oi the adiustnlcnt and hence, no matter what the projection of the dogs may be in the particular instance, the movement at the knee will be so limited that such diiio's cannot reach the saw line.
in it euro more is shown a c-tmstructiou in which the d are limited to a single path of movement beyond the face of the lance. in this :liorm the lance 29 COUPMZLJIIQH with a head block 30 in the usual manner and is provided with a lined guide 31 in. which the dogs 32 are movable through n'icclumism indicated ,grcneraliy at 33 and requiring; no specilic desrriplimi for the purposes oil this invention. ll cre the dogs only have one path o'l movemcnt beyond the face of the knee. There is no variable il'actor in the dog); movement because the (logos are not capable oi" more than one operative path in advance ot the taco oi? the knee. llfhcreipre, the knee iiliintcrrupted in its advancing movement at a point which will prevent the does in their single path cit umrement from reaching the saw line, will (:Hl'l'y out the purposes of the 1 sent iuven tioi. r0 ecoiunnically and practically provide for this result, the lined guide 31 is extciiu'lod below the knee as an abutment 3t which is adapted, in the movement of the lance, to cooperate with a stop 35 on the head block. lhe lance cannot advance beyond the limit position defined by the coo iicratien ot the abutment and stop 35. the dogs are movable only in one path in advance oil the line: and the position of the stop 35 is such as to interrupt the advancing; movement oi the knee before the dogs in their one op.- erativo position reach the saw line, it is apparent that such dogs cannot interfere with the operation of the saw.
lit is to be understood that the various forum here showi'i are indicatii e or" several types ol mechanirnns in which provision is made for either operating the dogs in a single path of movement or adjusting the does so that theymay operate in a maximum or mini mum path of movement. The mechanisms are illustrated merely to irulicate the adaptability oil? the present invention to such mechanisms, it being umlerstood that the invention as contemplated by the appended claim comprehcmis the relation of the movable stop, that is the element of the improved stop which is carried by and nmvable with the knee, to the mriablo 'lactor g)ermittin; the dog: adiustnmnt as will utilize this factor as the movable stop element. llllus the adjust meut ot the dogs controls the position of the hnce-rarried element oil the stopping mechanism. i
ll hat is claimed as new is:
in a saw mill carriage, a head block, a knee movable thereon, a dog-carrying frame arranged substantially parallel to the face oi the knee and mounted for movement relative to such face, a dog carried by and movable relative tosuch frame, means for moving the frame toward and from the face of the knee to adjust the dog for maximum or minimum projection beyond the face of the knee, and a stop on the head block, the dog-carrying frame providing a stop to cooperate with the stop on the head block when the knee has reached a position in its movement toward the saw line which will prevent the dog from encroaching on the saw line in either its minimum or maximum projection, the adjustment of the frame relative to the face of the knee determining the position of the kneecarried stop and of the projection of the (log beyond the face of the knee in relative accordance.
